      The K17 features an M21586Q DSP chip which iscapable of double- precision

      64-bit floating-pointcalculations, and runs at a high 360MHz clockfrequency.

      This chip is complemented by a highperformance ES9821Q

      ADC as well as a speciallycustomized ultra-low phase noise

      femtosecondcrystal oscillator. These three components

      allowthe user, in all modes, to utilize the 3l-band high,precision

      lossless PEQ. The PEQ is designed toensure the audio signal is

      still of high fidelity evenafter being processed. The chip also

      allows forrobust output protection functionality,

      ensuringthat headphones and other connected

      audioequipment are fully protected.

      31-band high-precision lossless PEO

      DEL (Dual Engine Limiter) technology together withproprietary

      algorithms allows the Kl7’s PEQ to becapable of dynamic range

      compression(DRC)/dynamic range expansion(DRE),limiter,

      andcompressor adjustment functions. PCM 44.1k~96ksignals can be

      processed in the PEQ without samplerate conversion.

      Fine adjustments of audioparameters are thus possible,allowing

      foradjustments such as a gain range of +12~-24dB and aQ

      value range of 0.4dB~128dB. The PEQ allows theuser

      to simulate or correct the frequency responsecurve PEQ settings

      can be easily exported, imported,shared, and saved - making it

      easy for anybody to usethe PEQ and correct or simulate various

      frequencyresponse curves of different headphones.

      An important part of the K17 is a carefully craftedfully discrete amplifier

      circuit for headphones. Thisdiscrete circuit is of an OP+

      transistor currentamplification design, equipped with the

      classic pairof ON Semiconductor MJE243/253 transistors.

      lt iscapable of producing high current with low outputimpedance.

      The result is up to 4000mW+4000mWoutput power

      in balanced mode, nearly double thatof the K9 Pro EsS. This allows it to easily

      drivevarious kinds of headphones and lEMs and

      toproduce smooth, pleasant. and natural sound.

      In the Kl7 is the flagship AKM DAC chipcombination-AK4191+

      AK4499EX*2. TWOAK4499EX chips handle each channel.

      The8-channel to 4-channel LPF designreduces common mode

      interference,resulting in better channel separation anddynamics.

      lt also features a newlydesigned architecture with fully

      separateddigital/analog3portions, which alsoincorporates the newly

      developed “DWAROUTING”technology for an evencleaner

      audio background and improvedresolution.

      Physically separated boards

      The various sections of the internal power supply,

      digital, andanalog sections are all located on physically separated

      circuitboards to avoid interference between them.

      This ensures theaccuracy and integrity of signal
